Using 11 frame foundationless Langstroth setups. Getting comb drawn across 2 frames; see no obvious reason it started on 2nd frame and carried thru. Assume solution is cut out those section(s) back to the guide on all concerned frames?

If it's pretty smooth just drawn at the wrong angle, just cut it off one frame and push it into a single frame. You can rubberband it in place as Allen suggest. Sometimes they'll mess it up bad enough that you just need to cut out some of it, and toss it.

why not just leave those frames just as they are??? I am new and have wandered the same thing. I did a cutout a while back an have two frames in this condition. I guess I feel the bees do very well with "comb management" in the wild, why should I interfere? I have decided to just leave those two frames as is

You would want to fix it while you can. That way maybe they will see how you want the comb running. I bought a hive, it was in bad shape, opened it after I got it home. It was 1 deep with a shallow super, the shallow super after getting cover off was just the box with a pint feeder in it. Well the rest of the box was filled with comb, going from the pint jar to the edges of the box.

The most important thing to grasp with any natural comb hive is that one good comb leads to another in the same way that one bad comb leads to another. You cannot afford to not be paying attention to how they start off. The most common cause of a mess of comb is leaving the queen cage in as they always start the first comb from that and then the mess begins. I can't believe how many people want to "play it safe" and hang the queen cage. They obviously can't grasp that it is almost a guarantee of failure to get the first comb started right, which without intervention is guaranteed to mean every comb in the hive will be messed up. Once you have a mess the most important thing is to make sure the LAST comb is straight as this is always the guide for the NEXT comb. You can't take a "hopeful" view that the bees will get back on track. They will not. You have to put them back on track.
